[pato]

can confirm I am encountering this error as well using cargo --version cargo 1.43.0 (3532cf738 2020-03-17)

the error happens while Compiling cargo-tarpaulin v0.12.3

[Quadriphobs1]

For now, I am using

docker run --security-opt seccomp=unconfined -v "${PWD}:/volume" xd009642/tarpaulin:develop-nightly bash -c 'cargo build && cargo tarpaulin -o Lcov'

[xd009642]

Looking at the stack trace are you trying to install for mac? If so Mac support isn't yet developed so it won't work

[Quadriphobs1]

Ohhhh, yeah its mac...

[xd009642]

There's a tracking issue for OSX support, it's definitely an area I'd appreciate some help with though I need to put more time into it! #152

[pato]

completely glossed over the fact that macOS is not supported! thanks for the info! will probably do in docker or CI then.

interesting, thanks for pointing to the state of macOS support I'll check it out!

[pato]

plus I have coverage working with CLion + Rust plugin on my Mac so I know it must be possible :)

[xd009642]

@pato that's probably with kcov, it has mac support!

I'm going to close this as the issue seems solved for you both 😄
